Range Cooker Connection Refusal.

Zoomup

A lady today asked me to estimate to do some cooker circuit alterations in her house. She has an old electric range cooker in the kitchen which she is to replace with a new one rated at about 11.2kW.

 

A certain national electrical retailer would not connect up her new and paid for range cooker as the cooker supply is run in 10.00mm2 T&E and protected by a B50 M.C.B. plus R.C.D.

 

The reason given was that the supply is too big and will overload the new cooker.

 

The retailer insisted that the  B50 M.C.B. be replaced by a B40 M.C.B. and the final cooker connection from connection unit to cooker, be run in 6.0mm2, the 10.002 final connection being removed.

 

Comments please.

 

Z.

    Look on the bright side, it does not yet impose a Zs limit, or that the supply is TT. 

    What this really tells you is that the cooker shop installers are just fitters, and have been told not to touch the set-up if it does not fit in with the pre-pack instructions. That is annoying but probably safer than if they were told they could  pick up a supply on any old red and black cable they could find. 

    It also frees up proper electricians to do something less soul destroying instead.

    I presume the OP just connected it up and it all works.
